Kuzya and Ustin are two of the five tiger cubs found in the Far-Eastern taiga some two years ago. The cubs were taken to a special rehabilitation center and later released into the wild.

The Siberian tiger, also known as Amur tiger, is on the Red List of Threatened Species. In 2010, Russia launched a national strategy to protect the Siberian tiger, the largest of the five tiger species. According to World Wildlife Fund, some 450 Siberian tigers are left on the planet.
